DEVICE FOR CLOSING BOTTLES.

SPECIFICATION forming part of Letters Patent No. 524,632, dated August14, 1894.

Application filed December 26, 1893. Serial No. 494,779. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM W. DIXON, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented new and useful Improvements in Devices for Closing Bottles, ofwhich the following is a specification.

This invention relates to certain improvements in that class of devicesfor closing bottles which are intended to prevent the fraudulentrefilling of the bottle with a liquid of inferior quality to that whichit originally contained.

The peculiar and novel construction of my device is pointed out in thefollowing specification and claims and illustrated in the accompanyingdrawings, in which- Figure l is a vertical central section when thebottle is in an upright position, the line a: a: Fig. 2 indicating theplane of section.

Fig. 2 is a transverse section in the plane y y Fig. 1. Fig. 3 is avertical central section when the bottle is inverted for pouring out itscontents. Fig. 4 is atransverse section in the plane 2 a Fig. 3. Fig. 5is a longitudinal section of the bottle in a downwardly inclinedposition.

In the drawings the letter A indicates the body of a bottle and B is theneck. In the neck is secured a tubular sheath 0 having near or at its.inner end a valve seat D the opening in which seat is adapted to beclosed by a valve E. This valve E is shown as a hollow cylindricalmetallic float valve which can be readily drawn or formed of sheet metaland closed by a cap or closure F soldered or secured to the valve.Within the valve E is shown placed a weight or ball G for a purpose tobe presently explained.

When the bottle is in upright position as in Fig. 1, the valve E dropsonto or closes the seat D, being led to its place by guides or arms Hwhich can be readily formed by bending or flanging the sheath 0 inwardat suitable parts, or the guides or arms H can manifestly be formed onthe valve E and the sheath 0 left cylindrical.

At the top of the tubular sheath 0 is a guard I closed at the top buthaving lateral openings K which allow the contents of the bottle to flowout but said guard prevents the introduction of a wire or tool down intothe neck 13 for the purpose of tampering with or improperly manipulatingthe valve E.

In the sheath O above the float valve E is a weight L having a flangewhich is segmental or partly cut away so as to form arms or teeth Mwhich slide or are guided along the sheath C, but the contents of thebottle can be poured out through the spaces between the arms M.

When the bottle is tilted to pour out the contents as in Fig. 5 theweight L will drop toward the guard I and the valve E will drop awayfrom the seat D so as to allow the contents to flow out of the bottle.Should the valve E stick or adhere somewhat to seat D as may occur forexample when the bottle contains saccharines or sticky liquids the ballor weight G dropping or rolling toward the cover F will produce a blowor jar which will cause the valve E to drop off seat D. When the bottleis turned to the upright position as in Fig. 1 the valve E drops ontoseat D and the weight L comes to rest on valve E. Should it be nowattempted to pour liquid into the bottle, such liquid will be preventedby valve E from passing through seat D as the weight L on valve E issufficient to overcome the power of flotation of valve E. If the bottleis reversed as in Fig. 3 and it is now attempted to force liquid upthrough neck B into the bottle, the liquid rising in neck 13 will floatthe valve E against seat D to close the latter, the power of weight Gnot being sufficient to overcome the power of flotation of valve E.

The sheath 0 can be secured or cemented in the neck B so as to beincapable of removal without breaking the neck or the bottle, and saidsheath can be further secured by a tubular lining N having a flange Oand secured in neck B. The bottle is filled before the sheath O isinserted and said bottle is intended for use only once. When filled andto be shipped or transported the neck can have a screw cap or a seal ortin foil P applied at its mouth in well known way.

The device can not only be applied to bottles but also to other vesselsas carboys, demijohns, and the like.

It is also to be noticed that in case the hotforated cup-shaped guard Ifixed within the sheath, and a loose gravitating weight L playingbetween the hollow cylinder and'theperforated guard, and provided withseparated flanges M, said weight operating to overcome the power offlotation of the hollow cylinder and to hold the latter down on thevalve-seat of the'sheath, substantial-lyas described.

2. In a device for preventing the fraudulent filling of a bottle orother vessel, the combination with a sheath having a valve seat, of ahollow float valve adapted to close the valve seat, a guard forpreventing tampering wlth the valve, 2.- weight made to act on theexterior of the valve, and a second weight placed in the interior of thevalve, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
